I would disagree. LEDs are solid state devices (light emitting diode) and are very susceptible to emp. If by automatic watch you are referring to anything with an LCD/LED display, you can kiss the electronics in those goodbye as well. I've smoked my Timex just by having it too close to a radiating antenna. It's not just about ICs, any solid state device is susceptible.

Obviously Spielberg and Wells never saw "When Mars Attacks" or they'd have brought Slim Whitman in to save the day. <img src="/images/graemlins/grin.gif" alt="" /> <img src="/images/graemlins/grin.gif" alt="" /> <img src="/images/graemlins/grin.gif" alt="" />
